Also set to take center stage at the event are French motorcycles, the BMW 507 and Simplex, one of the rarest of early 20th century marques.

The Concours selection committee meets at the end of March to determine which cars will get an invitation to the August 18 competition.

Organizers said the 2013 show field will focus on one-off, custom-bodied Lincolns, along with a display of "significant" one-off Lamborghinis. The Concours is also hooking up with the Porsche Museum to exhibit "some of the cars that have made this model iconic."
It is the 50th anniversary of Porsche.

The Concours will also celebrate the 100th anniversary of Aston Martin with a display of Aston Martins that have raced at Le Mans.

The BMW 507 will be one of the standouts at the event.

"The BMW 507 debuted to great acclaim in 1955, but the economics of producing this sporting roadster led to its all-too-early demise," show organizers said in a statement.

"Just over 200 of these cars survive and each is treasured. The only custom-bodied BMW 507s, along with other superlative examples of this model will be showcased.

The field of French motorcycles on display at Pebble Beach will include such manufacturers at Motobecane, Koehler-Escoffier and Peugeot.

Edmunds says: Excitement revs up for one of the key auto events of the year.
